Raise to Wake is such a simple and transformative new feature in iOS 10 that it feels like iPhones should have had it for years. Turning on the lock screen by just picking up your iPhone makes getting to notifications and apps quicker, but unless you have an iPad or iPhone released in the last year, you won’t get to enjoy it.

iOS 10 will only add the Raise to Wake feature to iOS devices with an M9 processor. The iPhone 6s, iPhone 6s Plus and iPhone SE are the only three devices that support the feature in the first beta build of iOS 10.

Even though both new iPad Pro sizes have an M9 processor, it appears that Apple is not bringing the feature to the tablet lineup yet. Raise to Wake is especially useful on devices with the second-generation Touch ID sensor that unlocks the device almost instantly, so you never even see your notifications.

Apple plans to release iOS 10 to the public this fall, bringing new whiz-bang features like a new Home app, redesigned lock screen, iMessage apps and effects, Rich Notifications and tons of smaller changes that overhaul the iPhone experience.
